Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile machinery, in particular to a push rod driving mechanism and a spare bobbin changing device for a textile machine. BACKGROUND

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby improving the long piece uniformity, reducing the weight unevenness, straightening the fibers in the sliver, reducing the hooks, making the fineness meet the requirements, and mixing different types or qualities of raw materials uniformly to achieve the specified mixing ratio. The automatic changing and replenishing function of the feeding bobbin of the drawing frame is one of the basic factors to realize continuous operation of the machine.

[0003] The drawing frame is an intermediate link in the spinning process and is a key process for improving yarn quality. In order to reduce the labor intensity of workers and labor costs, the existing drawing equipment has adopted a large number of automatic changing mechanisms. These mechanisms have a common feature, that is, each time the bobbin is changed, the bobbin is replenished, otherwise the machine cannot work continuously, which affects the improvement of work efficiency. With the development of technology, the drawing speed of the drawing frame is getting higher and higher, and the supporting mechanism also needs to keep pace with the times. The traditional spare bobbin mechanism cannot guarantee continuous work, the labor intensity of workers is high, and the production efficiency is limited. SUMMARY

[0004] 1. Technical problems to be solved by the present application

[0005] In view of the problem that the existing automatic bobbin changing mechanism of the drawing frame needs to replenish a bobbin every time the bobbin is changed, which cannot work continuously, the present application designs a push rod driving mechanism and a spare bobbin changing device for a textile machine, which can continuously replenish the bobbin through the driving assembly and the push rod assembly, so as to achieve the purpose of continuous work of the drawing frame.

[0006] 2. Technical scheme

[0007] In order to achieve the above purpose, the technical scheme provided by the present application is as follows:

[0008] A push rod drive mechanism includes a push rod assembly, a slide rail, and a drive assembly. The push rod assembly includes a push rod, a connecting plate, and a slider. The drive assembly includes a driving wheel, a driven wheel, and a conveyor belt. The driving wheel is generally rotatably connected to a drive motor and a reducer. The conveyor belt can be a belt or a chain. The corresponding driving wheel and driven wheel are suitable pulleys or gears. The driving wheel and driven wheel are respectively fixed to both ends of a base plate and are connected via the conveyor belt. The upper part of the slider is slidably connected to the slide rail through a through hole, and the lower part is fixedly connected to the connecting plate. The connecting plate is fixedly connected to the bottom belt of the conveyor belt, and the inner end of the connecting plate is fixedly connected to the transverse push rod. In practical use, the conveying function of the bottom belt of the conveyor belt can be fully utilized, and the reciprocating motor can be used to achieve reciprocating motion. The bottom belt of the conveyor belt does not need to rotate to the upper belt; the push rod driven by the bottom belt continuously replenishes multiple spare cylinders.

[0009] A further technical solution includes a push rod assembly that also includes a roller and a roller support; the connecting plate and the roller support are configured to cooperate and are detachably connected to the upper and lower surfaces of the conveyor belt bottom belt, respectively; the bottom of the roller support is connected to the roller via an axle; the roller is connected to the base plate, which improves the sliding of the conveyor belt bottom belt to rolling, making operation easier and increasing the number of spare cylinders pushed by the push rod by several times.

[0010] A further technical solution involves pressing a pad between the connecting plate and the upper surface of the bottom belt of the conveyor belt. The pad serves as a cushioning material to prevent excessive contact between the connecting plate and the bottom belt of the conveyor belt, which could damage the bottom belt.

[0011] A further technical solution involves a vertical rotating shaft rotatably connected to the inner end of the connecting plate. The upper part of the rotating shaft is detachably connected to a horizontal push rod, and a gear is fixedly connected to the bottom end of the rotating shaft. A pin hole is also drilled downwards through the left side of the push rod, and a pin passes through the pin hole. The bottom end of the pin passes through the right side of the connecting plate and is fixedly connected to the locking platform. A compression spring is wrapped around the middle of the pin. The gear can realize the rotation of the push rod. The cooperation of the pin, the locking platform, and the compression spring can realize the locking and unlocking of the push rod.

[0012] A further technical solution involves folding down the right side of the connecting plate to form a lower folding platform, which increases the tension stroke of the compression spring. A limit rod is also vertically fixed on the lower folding platform to prevent the push rod from over-rotating.

[0013] A spare bobbin changing device for textile machinery includes a base plate and a base plate arranged longitudinally and in parallel. One end of the base plate is fixed with the above push rod driving mechanism, and the other end is fixed with a pull pin plate and a rack that are respectively matched with a locking table and a gear. The cooperation of the two with the pin shaft, the locking table and the compression spring can realize the locking and unlocking of the push rod.

[0014] A further technical solution involves a Z-shaped folded plate with the upper folded plate bent downwards to form a curved plate, facilitating the operation of the clamping table.

[0015] A further technical solution involves a downward slope at the inner end of the curved plate, which facilitates the locking and loosening of the pin.

[0016] A further technical solution involves a protective cover covering the substrate, with a pre-drilled slit on the inner side plate of the protective cover for the push rod to move back and forth; the two ends of the slide rail are respectively fixedly connected to the two end faces of the protective cover.

[0017] A further advanced technical solution involves a downward-sloping outer end of the base plate, which reduces the effort required for operation.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0020] The present invention provides a spare bobbin replacement device for textile machinery, which can make full use of the conveying function of the bottom belt of the conveyor belt and achieve reciprocating motion through a reciprocating motor. The bottom belt of the conveyor belt does not need to rotate to the top belt. The bottom belt drives the push rod to continuously replenish multiple spare bobbins, thereby enabling the drawing frame to work continuously for a long time, improving work efficiency, reducing manual labor intensity, and laying the foundation for unmanned textile factories.

Detailed Implementation

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0033] Example 1

[0034] The push rod drive mechanism in this embodiment, such as Figure 1 As shown, it includes a push rod assembly 31, a slide rail 32, and a drive assembly 33; as Figure 2 , 3 As shown, the push rod assembly 31 includes a push rod 311, a connecting plate 312, and a slider 321; the drive assembly 33 includes a drive wheel 331, a driven wheel 332, and a conveyor belt 35. The drive wheel 331 is generally rotatably connected to a drive motor and a reducer. The conveyor belt 35 can be a belt or a chain. The corresponding drive wheel 331 and driven wheel 332 are adapted pulleys or gears. The drive wheel 331 and driven wheel 332 are respectively fixed to both ends of the base plate 2 and are connected by transmission through the conveyor belt 35. The upper part of the slider 321 is slidably connected to the slide rail rod 32 through a through hole, and the lower part is fixedly connected to the connecting plate 312. The connecting plate 312 is fixedly connected to the bottom belt of the conveyor belt 35, and the inner end of the connecting plate 312 is fixedly connected to the transverse push rod 311.

[0035] In this embodiment, the push rod drive mechanism can make full use of the conveying function of the bottom belt of the conveyor belt 35, and then achieve reciprocating motion through a reciprocating geared motor. The bottom belt of the conveyor belt 35 does not need to rotate to the upper belt. The push rod 311 driven by the bottom belt continuously replenishes multiple spare cylinders 9.

[0036] Example 2

[0037] The push rod drive mechanism in this embodiment has the same basic structure as in embodiment 1, but the differences or improvements are as follows: Figure 2, 3 As shown, the push rod assembly 31 also includes a roller 318 and a roller support 319. The connecting plate 312 and the roller support 319 are configured to cooperate and are detachably connected to the upper and lower surfaces of the bottom belt of the conveyor belt 35, respectively. The bottom of the roller support 319 is tumblingly connected to the roller 318 via an axle. The roller 318 is tumblingly connected to the base plate 2, improving the sliding of the bottom belt of the conveyor belt 35 to rolling, reducing friction, saving effort in operation, and increasing the number of spare cylinders 9 pushed by the push rod 311 by several times. Here, the roller 318 is not only a support wheel to prevent wear on the conveyor belt 35, but also plays a role in driving the push rod 311 forward or backward. A pad 351 is also pressed and fixed between the connecting plate 312 and the upper surface of the bottom belt of the conveyor belt 35. The pad 351 can be made of cushioning materials such as plastic and rubber to prevent the connecting plate 312 and the bottom belt of the conveyor belt 35 from being damaged by excessive contact.

[0038] The textile machinery spare bobbin changing device in this embodiment, such as Figure 1 , 4 As shown, the system includes a base plate 1 and a base plate 2 arranged longitudinally and parallel to each other. One end of the base plate 2 is fixed with the aforementioned push rod drive mechanism 3, and the other end is fixed with a pull pin plate 5 and a rack 6 respectively configured to cooperate with a locking table 317 and a gear 314. A vertical rotating shaft 313 is rotatably connected to the inner end of a connecting plate 312. The upper part of the rotating shaft 313 is detachably connected to a horizontal push rod 311, and a gear is fixedly connected to the bottom end of the rotating shaft 313. 314; The left side of the push rod 311 also has a pin hole extending downwards, through which a pin 315 passes. The bottom end of the pin 315 passes through the right side of the connecting plate 312 and is fixedly connected to the locking plate 317. A compression spring 316 surrounds the middle of the pin 315. The gear 314 can realize the rotation of the push rod 311. The cooperation of the pull plate 5, rack 6, pin 315, locking plate 317 and compression spring 316 can realize the locking and unlocking of the push rod 311. The right side of the connecting plate 312 is folded down to form a lower folding platform 3121, which increases the tensioning stroke of the compression spring 316. A limit rod 3122 is also vertically fixed on the lower folding platform 3121 to prevent the push rod 311 from over-rotating.

[0039] Example 3

[0040] The textile machinery spare bobbin changing device in this embodiment has the same basic structure as in embodiment 2, but the differences or improvements are as follows: Figure 6 As shown, the pin plate 5 is Z-shaped, with the upper part bending downwards to form a curved plate 51, facilitating the operation of the clamping table 317. The inner end of the curved plate 51 has a downward slope transition 511, realizing the transition between locking and releasing the pin 315. Figure 5As shown, a protective cover 7 is fitted onto the base plate 2. A cover slot 71 is reserved on the inner side plate of the protective cover 7 for the push rod 311 to move back and forth. The two ends of the slide rail rod 32 are fixedly connected to the two end faces of the protective cover 7, respectively. The outer end of the base plate 1 is a downward slope surface 11, which makes operation easier.

[0041] The spare bobbin changing device for textile machinery in this embodiment is applied to the main unit 10 of a drawing frame, such as... Figure 9 , 10 As shown, U-shaped plates 8 are mounted on both sides of the front end of the main unit 10. The U-shaped plates 8 are placed on the base plate 1. The driving wheel 331 is installed on the outer side wall of the bottom end of the U-shaped plate 8, and the driven wheel 332 is installed on the outer side wall of the top end of the U-shaped plate 8. The opening of the U-shaped plate 8 faces away from the main unit 10. One side of the main unit 10 is a storage channel for the spare cylinder 9, and the other side is a storage channel for the working cylinder 91. The main unit 10 is equipped with a photoelectric switch, which is located above the working cylinder 91 storage channel at the bottom end of the U-shaped plate 8. The lever 4 is mounted on the cylinder-controlled propulsion device and is located at the bottom end of the U-shaped plate 8, pushing the spare cylinder 9 from the spare cylinder channel to the working cylinder 91 storage channel. The photoelectric switch and the geared motor are respectively connected to the PLC controller.

[0042] In practical use, the working tube 91 runs on the main unit 10. When the cotton strip length reaches the set value, the working tube 91 is full and is pushed out by the pusher mechanism. After the lever 4 drives the spare tube 9 to the position of the working tube 91, it is triggered by the photoelectric switch, and the main unit 10 runs normally. At the same time, the lever 4 returns to the initial position. At this time, there is a gap at the spare tube 9. The photoelectric switch senses that there is no spare tube. The PLC controller controls the geared motor in the drive assembly 33 to drive the drive wheel 331, which drives the driven wheel 332 to rotate through the belt. The connecting plate 312 fixed on the belt drives the pusher 311 to move forward along the U-shaped plate 8, pushing the spare tube 9 to the bottom of the U-shaped plate. When all the spare tubes 9 are used up, the photoelectric switch is triggered, the geared motor reverses, and the connecting plate 312 and the pusher 311 move together towards the top of the U-shaped plate 8. Figure 7 As shown, during this process, after the pull pin plate 5 contacts the pin shaft 315, the clamping table 317 moves down along the slope transition 511 of the pull pin plate 5. The clamping table 317 drives the pin shaft 315 to unlock from the push rod 311, as shown. Figure 8 As shown, gear 314 and rack 6 mesh, and gear 314 drives push rod 311 to rotate around shaft 313 and retract into protective cover 7. After push rod 311 contacts proximity switch 21 inside protective cover 7, reduction motor stops running. At this time, after continuous cylinder replenishment is completed through downslope 11, reduction motor reverses, connecting plate 312 moves forward, gear 314 and rack 6 remain meshed, push rod 311 rotates out of protective cover 7, clamp 317 moves up along slope transition 511 of pull pin plate 5, and then pull pin plate 5 disengages from pin shaft 315. Under the action of compression spring 316, pin shaft 315 resets and locks push rod 311, and cylinder replenishment continues to circulate.

[0043] The spare bobbin changing device for textile machinery in this embodiment enables the drawing frame to work continuously for a long time, improving work efficiency, reducing manual labor intensity, and laying the foundation for unmanned textile factories.
